-
Adoption & Market Share: Polycrystalline panels became popular in the mid-2000s and made solar energy more affordable for homeowners. They still account for about 30% to 35% of the global solar market as of recent data. Their lower cost makes them a preferred option for residential installations in regions where upfront costs are a significant consideration.
-
Cost: The cost for a 5 kW polycrystalline system typically ranges between $12,500 and $16,000 in regions like Florida and Texas, where solar prices are more competitive. In contrast, the same system could cost $13,000 to $18,000 in New York, where labor costs and permitting fees are higher.
3. Thin-Film Solar Panels
Thin-film solar panels are created by depositing photovoltaic material onto a substrate like glass, plastic, or metal. These panels are lightweight, flexible, and can be integrated into a variety of surfaces, including windows and roofs.
-
Efficiency: Thin-film panels are the least efficient, with an efficiency rate of about 10% to 12%. While they require more space to produce the same amount of electricity as other types, their versatility makes them suitable for different applications.
-
Adoption & Market Share: Although thin-film technology represented a significant portion of the solar market in the 1990s and early 2000s, it has seen a decline in residential adoption. As of now, thin-film panels represent about 10% to 15% of the global solar market, with their primary use being in large-scale commercial projects and utility-scale solar farms.
-
Cost: Thin-film panels are generally the cheapest to manufacture, which makes them an affordable option for large-scale projects. However, due to their lower efficiency, they are less common in residential homes. Installation for a 5 kW system using thin-film panels could range from $10,000 to $15,000, depending on local labor costs and solar availability.
